Definitions
- Sample rate converters are for example used in an apparatus like a player, a recorder and/or a receiver for audio and/or video like for example Compact Disk players, Digital Audio Tape players and/or recorders, Television receivers, Digital Versatile Disk players and/or recorders etc., and/or are for example used in an apparatus like a video reproducer like for example monitors, displays, screens etc.
- the fixed sample rate increaser increases the input sample rate with a fixed increasing factor K, with the variable sample rate decreaser variably decreasing the intermediate sample rate with a variable decreasing factor L, with L ⁇ K.
- a filter located after the variable sample rate decreaser will be independent from the variable decreasing factor L and does not need to be adapted in dependence of this variable decreasing factor L. This is advantageous.
- the apparatus 10 according to the invention as shown in Fig. 4 comprises a sample rate converter 12 according to the invention located between at least one input unit 11 for receiving input information and at least one output unit 12 for generating output information.
- input unit 11 for example corresponds with a tuner and/or one or more amplifiers and/or one or more filters and or one or more converters, with output unit 12 corresponding with a display and/or a screen including one or more drivers.
